KYC is only helpful for people who are running the platform and somehow the government itself, it's sad that this data leaks will become a bigger problem if something is not done about it, this can't keep going on.
If you can not change the governments, you must adapt to what they enforce on you, and consequently you will have less choices for no KYC trades and platforms. You will have more difficulty to find no KYC platforms to use but it's all you can do for KYC adaptation.
Until a time you can have a politician, a party that have their propaganda as no KYC but honestly I don't see any government in the future will support no KYC. When there is no choice like that in your nation, you can not vote KYC government and politicians out of their power.
From now on I will change my view about KYC verification, I have never feel this way about passing KYC verification until today, I don't like it and I will never.
If you already did KYC one some platforms before, this mean your documents are stored somewhere and perhaps will be leaked in the future. You can change your practice from now with challenge I mentioned, but you can not completely erase your identity and documents which were submitted a long time ago.
